Abstract
A catalytic converter includes ring-shaped cushion members of differing bulk densities at each axial end of a catalyzer carrier, a first cushion member which is supported by a casing of the converter being of lesser bulk density than that of a second cushion member which is interposed between said first cushion member and the adjacent axial end of said catalyzer carrier.
Claims5
In a catalytic converter including a casing having an inner circumferential surface, a catalyzer carrier located within the casing and having opposite ends and end edges, support members located within the casing at the respective ends of the catalyzer carrier, annular metal rings engaged with the respective ends of the catalyzer carrier, and an annular cushion member supported by each support member and compressively engaged by the adjacent annular metal ring, the improvement comprising:
- at least one of said annular metal rings being comprised by a second cushion member having a bulk density which is higher than that of said first mentioned cushion member;
- said second cushion member being L-shaped in transverse cross-section including a radial flange engaged between said catalyzer carrier and said first cushion member, and a radially outer axial flange engaged with said inner surface of said casing and having an inner periphery sized so as to form a gap between said end edge of said catalyzer carrier and said inner periphery of said axial flange.
